Cov txheej txheem tsim khoom ntawm lub tshuab nqus tsev-brazed pob zeb diamond laum khoom

Cov txheej txheem tsim khoom ntawm lub tshuab nqus tsev-brazed pob zeb diamond laum khoom suav nrog cov kauj ruam hauv qab no:

1. Kev npaj substrate: Lub substrate, feem ntau yog ua los ntawm cov khoom siv hlau tsim nyog, yog npaj los ntawm kev ntxuav nws kom tshem tawm cov kab mob ntawm qhov chaw xws li xeb thiab roj.
2. Pob zeb diamond xaiv: Cov pob zeb zoo nkauj zoo nkauj nrog cov qoob loo tshwj xeeb raug xaiv raws li cov ntawv thov. Tom qab ntawd cov pob zeb diamond raug ntxuav kom ntseeg tau tias lawv tsis muaj impurities.
3. Kev npaj Brazing Alloy: Lub brazing alloy, uas tej zaum yuav muaj cov hlau xws li npib tsib xee, chromium, thiab lwm yam khoom, yog npaj. Qhov sib xyaw ntawm cov hlau nplaum yog qhov tseem ceeb rau kev ua tiav kev sib raug zoo nrog cov pob zeb diamond thiab cov substrate.
4. Pob zeb diamond txheej: Cov pob zeb diamond uas ntxuav tau yog teem rau ntawm lub substrate nyob rau hauv ib tug predetermined qauv. Kev faib cov pob zeb diamond yuav tsum ua kom pom kev ua haujlwm zoo.
5. Kev siv ntawm Brazing Alloy: Lub brazing alloy yog siv rau pob zeb diamond thiab substrate. Qhov no tuaj yeem ua tau los ntawm ntau txoj hauv kev, xws li kev tshuaj ntsuam luam ntawv, electroplating, lossis mechanical clamping.
6. Nqus Brazing Rauv Loading: Lub substrate nrog pob zeb diamond thiab brazing alloy yog muab tso rau hauv lub tshuab nqus tsev brazing rauv. Lub tshuab nqus tsev ib puag ncig yog qhov tseem ceeb los tiv thaiv oxidation thiab ua kom muaj kev sib raug zoo.
7. Vacuum thiab Temperature Control: Lub tshuab hluav taws xob tau khiav tawm los tsim lub tshuab nqus tsev, thiab tom qab ntawd ua kom sov rau qhov kub thiab txias. Qhov kub no yog ua tib zoo tswj kom yaj lub brazing alloy tsis ua rau lub pob zeb diamond.
8. Brazing: Raws li lub brazing alloy melts, nws ntub cov pob zeb diamond nto thiab cov substrate, tsim ib daim ntawv cog lus metallurgical. Lub cub tawg yog tuav ntawm qhov kub thiab txias rau lub sijhawm tshwj xeeb kom ntseeg tau tias muaj kev sib raug zoo.
9. Txias: Tom qab cov txheej txheem brazing, lub cub tawg tau txias kom maj mam tso cai rau lub brazing alloy kom ruaj khov thiab txo qis thermal stress ntawm pob zeb diamond thiab substrate.
10. Kev tshuaj xyuas thiab kev tswj xyuas zoo: Thaum txias, lub tshuab nqus tsev-brazed pob zeb diamond laum me ntsis raug tshem tawm ntawm lub cub tawg thiab tshuaj xyuas kom zoo. Qhov no suav nrog kev txheeb xyuas qhov sib xws ntawm cov hlau alloy, kev ncaj ncees ntawm daim ntawv cog lus, thiab tuav lub pob zeb diamond.
11. Kev ua haujlwm tom qab Brazing: Cov kauj ruam ntxiv xws li kev sib tsoo lossis lapping yuav raug ua kom ntseeg tau tias lub laum me ntsis muaj qhov tseeb geometry thiab tshem tawm tej qhov chaw siab lossis qhov tsis sib xws.
12. Ntim: Lub tshuab nqus tsev zaum kawg-brazed pob zeb diamond laum me ntsis yog ntxuav, tshuaj xyuas kom paub tseeb qhov zoo, thiab tom qab ntawd ntim rau kev faib khoom lossis siv ntxiv.

Cov txheej txheem no ua rau muaj kev xyaum me ntsis nrog cov pob zeb diamond sib koom ua ke rau lub substrate, muab kev ua tau zoo dua qub thiab siv tau ntev dua piv rau cov khoom siv laum ua nrog lwm txoj kev txuas. Lub tshuab nqus tsev brazing txheej txheem yog tshwj xeeb tshaj yog rau cov ntawv thov uas yuav tsum tau drilling rau hauv cov ntaub ntawv nyuaj.
